Help Wanted - Silver Soldering Master Class

(1/4) > >>

Hello All,

I'm hoping this is the correct place for this post!

I have some (relatively limited) experience with silver soldering, mostly small brass/bronze fittings and copper tubing for my steam locomotive. I would definitely consider myself a novice overall.

For 2023 I would like to improve my silver soldering skills and techniques. I see some really clean work here and on other forums and I am always jealous when I see the very skilled workmanship!

So the question is; does anyone know of a "master class" type of resource for learning better silver soldering techniques and skills?

I'm open to any and all suggestions - books, YouTube videos, jewelry making resources, etc. etc.

Things I would like to improve:

* fixturing techniques and tools
* proper application of flux and heat
* advanced techniques such as complex soldering of built up parts with multiple components and soldering large components.

I hope this doesn't sound too trite, but only two things are important. Practice, and applying enough heat! Get yourself some vermiculite blocks and surround your work with them, and fit a big enough burner to get the work red hot in  a short time so you don't deplete the flux.
Hope this helps.

Have you seen any of the Kozo Hiraoka books on building locomotive models? They have a lot of that type of information. Thats where I learned most of what I know about silver soldering and fixturing.

On this forum there is currently a build titled 'Pennsylvania A3 Switcher (Kozo)' by 'Kim' that is building from one of his books, he is going through a lot of the same learning on silver soldering that you are asking about, there are lots of posts over the last few months dealing with just that.

Other than that, its a pretty broad topic, lots of people here would be glad to help with specific questions, I'm sure. A lot comes down to practice, as John said, plus help on specific setups/tools depending on what parts you are trying to make. I don't know of a specific class or thread on just that topic, since a lot depends on what size/metal parts you are trying to do, and what tools you have.

my biggest hint is to solder in a darkened room, it allows you to see the glow and temp of the parts better, you can see where more heat is needed and where parts are getting to hot..

Try also Tubal Caine's "Soldering and Brazing".  (The Model Engineer Tubal Caine, Tom Walshaw, not the present YouTube incarnation). It's Number 9 in the Workshop Practice series. Very reasonably priced.
